System could provide first method for filtering light waves based on direction Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive. But now, for the first time, MIT researchers have produced a system that allows light of any color to pass through...

...but scientists propose a simple fix Solar power might be nature's most plentiful and benign source of energy, but shiny black solar cells can lure water insects away from critical breeding areas, a Michigan State University scientist and colleagues warn. Applying white grids or other methods to break up the polarized reflection of light, however, makes mayflies and other aquatic insects far less likely to deposit eggs on the panels thinking that they are water, the group discovered. "This...
